PAPER-FEED ATTACHMENT FOR TYPE-WRITERS.

Specification of Letters Patent.

Patented Jan, 18, 1910.

Application filed January 19, 1909. Serial N 0. 478,173;

To all whom it may concern: Be it known that LWrnnnrRrnenLrDrxon, acitizen of the United States, residing at Roanoke, in the county ofRoanoke and State of Virginia, have invented a new and useful Paper-FeedAttachment for Typeriters, of which the following is a specification.

This invention has reference to improvements in paper feed attachmentsfor typewriters and is designed to provide a reservoir for sheets ofpaper to be fed successively and automatically to the platen intoposition to be operated upon by the type without the necessity of theoperator placing the sheets as needed; v.

The invention is designed particularly for the feeding of sheets ofpaper, where many sheets are to be used, in succession and rapidly, thespeed of the use of the machine being thus greatly augmented by avoidingthe necessity of the operator stopping the typewrit-ing in order tochange the sheets.

The present invention isdesigned to be attached to any of the commercialforms of typewriters, being connected directly to the carriage andprovision is made for the feeding of the sheets one at a time'and insuccession to the proper side of the platen, the feeding bein performedautomatically byand in accor ance with the movements of the platen inthe act of typewriting. The structure is such that when a sheet isremoved from the typewriting machine the next sheet has already beenautomatically moved into position with relation to the platen tocontinue the typewriting.

The invention will be best understood from a consideration of thefollowing detail description taken in connection with the accompanyingdrawings forming a part of this specification in which drawings,

Figure 1 is a perspective view of the at tachment applied to thecarriage of a cominercial form of typewriting machine, Fig.

'- 2 is a:vertic'al section through the structure shown in Fi I. Fig. 3is a plan View of a portion .of t e reservoir with the cover removed and,with' parts shown in section. Fig. 4 is a detail section showin theactw ating gearing for the feeding r0 er forthe paper Fig. 5 is a detailv ew-showing a form of support for the attachment adapting it to adifferent type of typewriter machine than shown in Fig. l. '6 is adetail view of a support for the end of the deed roller remote from theactuating end.

Referring to the drawings there is shown a typewriter carriage 1 whichmay be taken as typical of any typewriter carriage and the platen of thecarriage is indicated at 2.

Fastto' a portion of the rear of the carriage near each. end thereof isa block 3 in the upper end of which is formed a socket for socket bymeans of a thumb screw 5 so'that therod may be readily inserted orremoved" at will without the use of. tools. A set screw 6- serves toholdtheblock 3 in place since it is notnecessary to remove the block inorder to remove the attachment and the block may therefore be considered"ass permanenthttachment to the typewriter carriage"if so desired. -Theupper end of the an angle away rod 4 is flattened and bent at from theplaten and is provided with two holes for the passage of bolts 7.

The rods'l, there being two such rods, one near each end of thetypewriter carriage, serve, as a support for a reservoir 8. The heads ofthe bolts 7 where they eittend through the. v slots 9 through thecorresponding wall of the reservoir .so that a certain amount ofadjustment is provided for setting the reservoir to proper relation tothe platen'fland after the adjustment has been made then the nuts ofthebolts may be tightened, thereby holding the reservoir in properposit-ion.

The reservoir is shown as U-shaped in cross-section and is as long orslightly longer than the used. The 0 en end of the reservoir is towardthe platen as indicated in Fig. 2

and fast to the lower side of the reservoir the-reception of ii rod 4:held in the walls of the reservoir 8 play in width of the paper to be 8is a low partitionlt) which may extende11 tirely' across the l, on ismuch shorter than the lower face and .to

eservoir if so desired and} the end of the upper face there is hinged acontinuation 12 in the nature of a cover and this continuation or coveris provided with a projecting lip 13 inclined downward at an angle tothenia n portion of the cover 12 for a purpose which will presentlyappear, while the free edge 14 of the lip 13 is bent at an angle to thelip, as indicated in Fig. 2.

' there engaged by springs 18 each connected.

to the corresponding end of the rod 15 at one end and at the other endto a suitable portibn of the reservoir 8. The tendency ofthe springs 18is to move the cover 12 toward the other side of the reservoir for apurpose which will presently appear.

At one end of the reservoir there is a casing 19 housing two gear wheels20 and 21 in mesh one with the other. wheel 21 is formed with or hassecured to it a stub shaft 22 extending through the corresponding endwall of the reservoir 8 and terminating in a squared section 23 within.

said reservoir. This squared section 'is adapted to enter a squaresocket-in a roller 24 within the reservoir beneath the cover 12 adjacentto the point of junction with the cover of the lip 13. The other end ofthis-roller is supported in a bracket 25 shownseparately in Fig. 6. Thisbracket is designed to be riveted or otherwise secured to the other endof the reservoir on the inner face thereof and is provided with a socket26 adapted to receive an axial stud on the corresponding end of theroller.

hen the cover 12 is lifted then the .roller 24 may be readily removed bydisconnecting it from the bracket 25 and then pulling it away from thesquared portion 23 of the stub shaft 22.

shaft27 and on this shaft exterior to the casing 19 there is mounted asprocket wheel 28 having a clutch member 29 on the side thereof remotefrom 'the casing 19. This sprocket wheel 28 is free to rotate .on theshaft 27 but may be coupled thereto by another clutch member 30rotatable with the shaft'but also capable of sliding'thereon. The clutchmember 30 is ur ed constantly toward the clutch member 29 by a spring 31surrounding the shaft27 and confined between said clutch member 30 and ahead32 formed on the outer end of the shaft. I

" The clutch member 30 carries a collar 33 in which the clutch member 30is rotatable and this collar is engaged by a fork 34 straddling thecollar and connected thereto by pins 35 at diametrically oppositepoints. The fork 34 is fast to one end of a lever 36 pivotedto a bracket37 projecting from the corresponding end wall of the reservoir 8. Thisbracket also carries a spring member 38 normally tending toward thebracket 37 The gear and mounted on the side thereof remote from thelever 36. The spring 38 is provided with a projecting finger or stud 39adapted to be brought into the path of the lever 36 on either sidethereof. 1

When the lever 36 is moved in a direction ,to separate the clutchmembers, which movement is against the action of the spring 31 thefinger 39 will maintain the lever in such position. I When it is desiredto bring the clutch members together it is only necessary to move thespring 38 in a direction to carry the finger 39 out of. the path of thelever 36 when the spring a 31 will cause the two clutch members to bebrought into engagement thus coupling the sprocket wheel 28 to the shaft27.

Mounted on the;arbor of the platen 2 is a sprocket wheel 40 and thesprocket wheels 28 and 40 are connected together by a sprocket chain 41,the continuity of which may be broken by the separable coupling 42.providedfor the ready separation of the chain when it is desired toremove the attachment 3 from the typewriter and for 'the ready couplingof the end of the chain when it is deslred to installthe. attachment onthe type-.

of the chain avoids the necessity of dismantling the typewriter carriageto the extent of disconnecting the platen 2 therefrom; Whenever theplaten 2 is rotated then, the gear wheel 27 is likewise rotated if theclutch members 29 and 30 be in engagement, and this rotation is impartedto the roller 24 through the gears 20 and 21.

Within the reservoir .8 there is located a follower 43 under the controlof two spaced thumb screws 44 each having a threaded bearing in thepartition 10 before referred to, so that the follower 43 may be moved toThe gear wheel 21 is mounted on a stub and from the partition at thewill of'the operatorI The inner face of that portion bf the reservoirover which the follower 43 travels is provided with index markings 45 sothat the follower may be adjusted for paper sheets of difiereut lengths.Upon each thumb screw 44 there is a clamp nut 46 so that when thefollower 43 is adjusted the thumb screws may be locked in placethusinsuring the maintenance of the adjustment of the follower 43.

.writer. The ready coupling or uncoupling Extending from the lowerportion of the reservoir down to a point close to the platen 2 is anapron 47 secured to the post 4'by one of the bolts 7 in each post. Theouter surface of the roller 24, as well as the inner surface of thecover 12 is rough ened preferably though not necessarily by theapplication of emery thereto. Thisemery surface which maybe produced bythe application of emery owder and a suitable cement is shown'on t eroller at 48 in Fig.

4 and on the cover at 49- in Fig. 4. 3 Within the reservoir there isshown a stack.

sea /2e of sheets 50 of the paper to be used'with the typewriter. Inorder to place these sheets of paper in the reservoir the cover 12 israised and the roller 24 is removed after which the sheets of paper bentinto U form are introduced into the reservoir with the the stack ofsheets is sufliciently elevated the roller 24 is replaced"'and then thecover is brought down so that the roller will engage the innermost sheetof thestacli, the latterbeing held to the roller by the Tet-motive forceof the springs 18. The follower-43 is adjusted to conform to the lengthof the sheet so that the overlapping ends will be brought intoengagement with the lip 13 as indicated generally in Fig. 2. It now theplaten 2 be turned in the direction necessary to feed a sheet of paperaround the same the motion is transmitted through the chain 41 to thegear-wheel 21,. the clutch members being then in engagement, and thismotion is imparted "to the roller 24 in a direction however the reverseof the direction of rotation of the platen '2 so that the roller 24:will.

tend td move the adjacent sheet of the paper in a direction out of thereservoir and under the li 13 when it is directed toward the apron 4 bythe continuation 14 of the lip 13 and-is ultimately guided into positionto be fed to the platen and engaged by the same in the usual manner.

Let it be assumed tha-ta sheet of paper has 7 alreadynbeen fedto theplaten and that anothersheet is being fed thereto as indicated in Fig.2. It will be noticed that the second. sheet overlaps the'firstsheet fora distanceso that by the-time the-first sheethas' bee n moved out ot theline of the type the second sheet has been moved into the line of thetype witha suitable upper margin. This is due to the overlapping of theshee'ts'at the I feed endof the reservoir since whe a sheet escapesfromthei'oller 24 the next ceding sheet for a like distance;

in the reservoir. it As the sheets are fed out fromthe' reservoir thenext succeeding sheets new supply maybe quickl are lrept in Contact withthe roller 24 by the action of the springs 18 moving the. cover 12'toward the said roller,

When the sheets have become manner already describe Should it be eet isengaged at a point somewhat distant from its end so that it. tends tooverla; the pre'- his-is dueto the manner of supporting the sheetswithexhausteda inserted in the desired to: use sheets of a greater orshorter length than-those for which the'reservoir is first set, .the'follower 43 may be readily adjusted to accommodate such sheets so thatthe overlapping ends have always the same relation to the roller 24, andthe follower 43 also serves, for the alining of the corresponding endsof the sheets without attention on the partof the operator.

The attachment is adapted for difi'erent commercial forms of typewritersandin Fig. 5 is shown a'block 3 whereby the attachment may be connectedto the typewriter carriage of a different style of typewriter than-thatshown in Fig. 1. This may be taken as indicativeof the manner ofconmeeting the atta'chmentto different styles of typewriters and it willtherefore be unnecessary to show other forms of connecting blocks sincethe only change in the structure needed to adapt the attachment tovarious makes of typewriters is in the form of the attaching block 3 03.,
